I have my 3rd blood creatinine test tomorrow. Both so far have been 1.1, I had a massage yesterday, will this effect the test? It was not a deep tissue massage. It was just a regular massage, but they do take care of your issues with the stress knots in shoulders and neck. I am sore today. I have my test tomorrow. PLease let me know. I worry about things.

I don't believe that it will affect the test. On the other hand, you could make sure to hydrate well before tomorrow and that will help also. When getting kidney function tests, always make sure you keep yourself hydrated before the labs. Not being hydrated can skew the results so if you make sure to drink the same amount roughly before each test you know any changes will be accurate, not due to water balance.

You mention three tests, however, you do not mention the reason for this frequency. Have you been having symptoms that prompted you to test for kidney function? Depending on your body mass, 1.1 creatinine might not be too high, even for your age (creatinine tends to decrease with age, in healthy individuals). I have measured as high as 1.1, which gave me an eGFR of 71. I have had many blood tests in the last two years, for a variety of health issues, and my creatinine usually runs at 1.0.

Deanne, creatinine tends to increase with age, gfr tends to decrease. All this indicates a slightly lower kidney function.

Lower muscle mass in older people can give lower creatinine readings. Lower eGFR readings may be clinically insignificant, and therefore, not give rise to pathological markers, as in significanly increased creatinine. Muscle mass does figure in creatinine levels, which is why a bulky body builder can show readings in excess of 1.2, and not be kidney impaired.

The issue of lower muscle mass is true, but it is also true that kidney function declines with age and most docs do not blink at an elevation of cr. in a senior.
